Default 2003 with PHP Hydra- hunting gears

2003 F-250 4R100- Just purchased Hydra with PHP library tunes from 1023. Installed good no issues. box code VDH5, actual Hex code TNAA7S3 using recommended hex of TNAA4S2

The only issue I have experienced is that on many of the tunes while driving 65mph if I mat the throttle to WOT the trans will downshift as expected then immediately upshift then back down and up again. it will continue this until I left off or up on the throttle. I have tested on nearly all tunes 65HP and higher with the same result. Stock tune does not do this. I have not checked the tunes between stock and 65hp yet. I am running all stock valve body tunes but for testing I did install 2 80hp tunes with modified VB tunes. Still hunts for gear in this condition. Truck makes good power and drives very nice with the tunes. This appears to be the only issue.
I can do any testing needed and fairly knowledge about these trucks (tjbeggs on FTE). Let me know what you need to know to help solve this issues. Thanks!
